3 Claims.

This invention relates to quoins, such as are used for locking a columnof slugs in a printing galley,'and contemplates an improved form ofquoin Aand one which is particularly adapted for 5,; locking up very lowless-than-type-high slugs in a specially constructed shallow galley.These special galleys and low slugs are of recent development, beingintended primarily for the printing of telephone directories and thelike (see the :191; Frolander application, Serial No. 490,141, filedOct. 21, 1930 which is now Patent No. 1,903,507,

dated Apr. 11, 1933). Y

`The general object of the present invention is to provide a quoin whichwill be of light weight yet j; strong and durable, which is capable ofbeing economically manufactured in standardized form, andr which, willbe thoroughly effective and efiicient in operation. With these ends inview, the improved quoin comprises two members normal- MTI 1y heldtogether in telescopic relation and adapted, to be expanded by movementof the members in opposite directions. Specically, the quoin consists ofan open-end box-like structure or housing, and a block adapted to fitwithin the 2g; housing and held in telescopic relation therewith bysprings. An eccentric or cam is also located within the housing in suchrelation to the two members as to act, when turned by a key, to forcethe inner member outwardly against the tension 'ni of springs pullinginwardly thereon.

In the accompanying drawings, the invention is illustrated merely by wayof example and in preferred form, and obviously many variations andmodifications may be made therein which will i still be comprised withinits spirit. It is to be understood, therefore, that the invention is notlimited to any specific form or embodiment, except insofar assuchlimitations are specified in the appended claims.

V Referring to the drawings:

Fig. 5 is a perspective view of the blank from which the quoin bankingblock is formed; and

Fig. 6 is a perspective view of the assembled banking block.

Referring to Fig. l, the shallow galley A com- 30 prises a bottom A1 andfour side walls A2, A3, A* and A5, the galley being divided into vecolumns a1, a2, a3, a4 and a5 by a number of partitions b. Thesepartitions b are secured to the bottom A1 of the galley and are formedwith beaded tops b1 65 (see Fig. 2) adapted to t into notches m formedin the ends of the low slugs M; and at each side A2 and A4 of thegalley, there is provided a corresponding rib b2. Due to the fact thatcolumns of different lengths are set up in the galley, it is necessarythat .the quoins C, used for clamping the slugs in each column tightlytogether, be backed up sometimes by banking blocks, and in the ordinarygalley this is accomplished by filling in the entire space between theend wall of the 75 galley and the quoin with suitable blocks. However,in the type of galley illustrated, a single banking block, such as theblock D, is used, having a pin p (Fig. 3) projecting from its undersideand adapted to be fitted into one or another of a number of perforationsP formed in the bottom A1 of the galley, these perforations being spacedapart so that the quoin C may always be placed in a position to functioneffectively.

It should be stated that the present invention 35 is not concerned withthe galley and slugs briefly described in the foregoing, nor with ameans for locking up columns lof slugs in the galley, but rather isconfined to the particular construction of the locking quoin C and thebanking block D adapted to be used in connection with the galley.

As already stated, the quoin C is composed ofr two main sections, anouter box-like structure or housing 10 (Fig. 4) andan inner plate-likestructure 11, which latter is adapted to fit within the 96 housing 10and to be held in telescopic relation therewith by a pair of coilsprings 12 and 13, an interposed floating camV or eccentric 14 beingadapted, upon rotation, to move the inner member 1l antagonistically tothe springs l2 and 13 100 to project the forward end thereof outwardlyfrom the housing 10. In this manner, the quoin C may be expanded varyingdegrees to lock up a column of slugs, the eccentric being held in itslocking position by friction.

The outer box-like structure or housing 10 comprises a solid bottom wall25, end walls 26 and 27, a rear wall 28, and a top wall 29, the housingbeing left open at the front. Eyelets 30 and 31 are formedvin the rearwall 28 of the housing to 110 vasf the rear edge of the member.

serve as anchors for the rear ends of the springs 12 and 13,respectively, and in order to facilitate the attachment of the springsto the eyelets, the top wall 29 of the housing 1() is formed above eacheyelet with an opening 32. rIhus, when the quoin is being assembled, theholes 32 permit access tothe interior of the housing so that, a pair ofpinchers or other suitable instruments may be inserted to take hold ofthe springs 12 and 13 and attach them to the eyelets 30 and 31. The topwall 29 of the housing 10 is also formed with a central fore-and-aftslot or opening 33, the purpose of which will later appear.

Although the housing 10 may be manufactured in any suitable manner, itis preferably made from a stamped-out sheet metal blank C1, such as isindicated by dot-and-dash lines of Fig. 4, which is folded or diepressed into the final form illustrated by the full lines in thatiigure.

The inner member 1l is also preferably stamped in one piece rom a sheetof metal, being cut to provide a central curved opening 16 and twoforeand-aft slots 17 and 18, one at each side of the central opening 16,all three extending through At their inner ends, the slots 1'7 and 13are provided with cross pins 20 and 2l, respectively, which serve asanchors for the front ends of the springs 12 and 13.

' In assembling the quoin C, the eccentric 14 is positioned in thecentral opening 16 of the member 11 and the front ends of the springs 12and 13 anchored to the cross pins 20 and 21. The members 10 and 11 arethen telescoped and the rear ends of the springs 12 and 13 attached tothe eyelets and 31, the attachment of the springs to the eyelets beingfacilitated by the openings 32, before alluded to.

When assembled, the eccentric 14 projects rearwardly beyond the rearedge of the memberll and bears against the inner face of the rear wall28 of the member 10, being held in this position under pressure of thesprings 12 and 13, which are always under suflicient tension to maintainthe members 10 and l1 in telescopic relation. A key "L socket 15,centrally located in the eccentric 14, is

exposed through the fore-and-aft opening 33 provided in the top wallofthe member l0, so that a key K may be inserted in the socket forrotating the. eccentric, and so that upon rotation the key will be freeto reciprocate in the opening 33 as required by' the throw of theeccentric.

' VIn order that the eccentric 14 may be rotated in but one direction,it is formed with two oppositely located lugs 40 and 41, one of whichwill bank against an abutment 42 formed in the wall of lthe opening 16,dependent upon which lug happens to be located adjacent the abutment atthe time of assembly.

Referring to Figs. 5 and 6, the adjustable banking block D is preferablystamped in one piece from a sheet of metal and folded to form a hollow'rectangular block, open at opposite ends and having parallel top andbottom walls 45 and 46, respectively, a back wall 47, and a partiallyopen front wall formed by three lips 43, 49, and 50, which are bent atright angles to the top wall 45 and have their ends engaging the upperface of the bottom wall 46. When the blank for the block D is stampedout, two circular holes 51 and 52 are cut in the top and bottom walls 45and 46, respectively, so as to' be in vertical alinement when the blankis folded to make up the block. These holes 51 and 52 are adapted toreceive and hold the pin p, which projects below the bottom wall 46 sothat it may i'lt in one'or another of the perfora- Because of its smallsize, and in order to maintain a high degree of efficiency, the throw ofthe eccentric 14 is not very great, and under these circumstances itwould ordinarily be necessary to .locate the perforations P in thebottom of the galley quite close together in order to take care of allvarying column lengths. To overcome this necessity (as a result of whichthe galley bottom between the perforations would be considerablyweakened), the pin p is located off center of the banking block D,whereby the latter may be placed in the galley with either its frontwall,

consisting of the lips 43, 49 and 50, or its rearl wall 47 in positionto be banked against by theA quoin C, as shown in columnsa4 and a5 inFig. 1. Since the columns of slugs to be locked up are not always of thesame'length, it has heretofore been necessary to employ'furnitureY to'build up the columns between the backs of the quoins and the end of thegalley, but according. to the construction of the galley with which theimproved quoin and banking block are used, the banking block isadjustable in-the galley. Thus, if a short column of slugs, such ascolumn a3 shown in Fig. 1, is to be locked up, the quoin C and thebanking block D are placed in the columny with the. pin p seated in oneofthe upper perforations P, so that there is only a small space, such asindicated at s, between the last slug M of the column and the forwardend of the innerv member 11 of the quoin C. The banking block D fits inthe column with the extensions 53 and 54 of the bottom wall 46 thereofengaging bel tween the beads b1 of the partitions b in sub-Y stantiallythe same manner as the lower portions m of the `opposite ends of .theslugs M (see Fig. 2), thereby preventing any upward displacementof thebanking block when pressure is applied thereon in locking up the columnof slugs.

To expand the quoin C for locking up the column of slugs, the key K isinserted in the socket 15 formed in the cam or eccentric 14 and turnedin a clockwise direction so that the eccentric will force the innermember 11 antagor'iistically tothe springs 12 and 13 up against thecolumn of slugs N, whereby the latter willybe locked firmly in placeuntil the. eccentric is manually released.

It will be noted that in some cases,A as when the column of slugs is offull length, usuch`as column a2, the banking block D is unnecessary, thequoin C banking directly against the end wall A5 of the galley A.

As stated before, the invention is 'illustrated merely in preferred formand by way of example, and obviously many variations and modificationsmay be made therein without departing from its spirit. For example, thequoin and ,banking block have been illustrated and described as smalland particularly adapted for use inconnection with low slugs and aspecially constructed galley, but with little or no modification theymay be readily adapted for use with regular or full type-high slugsandgalleys. It is to be un-1 derstood, therefore, that the invention isnot to be limited to any specific form or constructionV except insofaras such limitations are specified in the appended claims.

Having thus described my invention, what I claim is:
